T0 ALL WHOM IT MAY CONCERN; l

Be it k'noirn that I, B. G. FITZIIUGH, of th'c city of Baltimore, andState of Maryland, have invented `certainne'w and'usefulimprovemczxts'in Burglars Alarms, for the doors of safes, vaults, rooms,and other aparti ments or receptacles where valu 'ibles are kept; and Ido hereby deelare the following to be a full, clear, and

exact description oflthe same, reference being had t-o the accompanyingdrawings, in which- Figure 1 represents a top plan; and l Figure 12v avertical section of so much of a vault, safe, or other apartment, aswill illustrate my invention.

I uur-.aware that many kinds of alarms-have been used in connection withdoors, windows, &c., so that the opcningfof suchdoors or vvindons willsound an alarm or tire ofi' a charge; but in all these cases the alarmor'triggcrthat sets them off must be arranged or set-by a. person on theinside of such door, Window, or apartmeut, .und which, in the case ofsai'es' or vaults, is impracticable; 'andif arranged from the outside,the burglar or dthelp'erson forcing or attempting to force the door mayalso from 'theoutsidc disconnect said alarm or lirearn), and thus renderit inoperative for the purpose.

My'inventiou consist's'in placing an alarm on the inside of a safe,vault, or other receptacle or apartment, and so connecting thcdoor of`such safe, vault, room, or other apartment with it, that the act ofyclosing said doorfrom the outside shalllconnectit with the alarm orrearin,.and the opening of said door'froni the outside l set off thealarm" or tire-arm.

"To enable others skilled in the artto make and use my invention, I willproceed to describe the same, with reference the drawings.

' A rcprescntsfthe interior of a safe, vault, or other receptacle orapartment' in which valuables are kept, and the door, B, of vwhichswings outward. is a look, such as are used on any firearm, and composedof a hammer, a, nipple, Il, and the ordinary appliances for holding thehammer at the cbck, and lettingy it of by tripping thedog or sere. c care guides arranged nearthe lock, and beyond them a cam or .inclinedledge, d, ivhiclralso acts as a guide, as iiill-be explained. vTo thedoo'r B of the safe, vault, or other-apartment, and on theinside-thereof, is pivoted, as at e, a Jever, D, having-i upon itsextreme end va wedge or cam-shaped projectiomf, and in or on said leverthere is :ilso'a pin or stud, e', to guide it in thepropcr direction toconnect it with the lock C.; The lever D is piroted or hinged to allowit to have two motions, rst longitudinally and then laterally,toc'onncct with the dog or sere leverg as it is moved invvard by theclosing of the door B, and also that it maybe swung around out of action(as shown by the dotted lines in iig. l) during the day and when thcalarm is not required to be used. When the alarm is to be -used orconnected with the door, the nipple 6 is capped, and if a barrel isconnected to it the latter may bev loaded. The hammer a is set at thefull cock, and tl1e pin or stud z'oi` the lever D being placed betweenthe guides'c o, the door of the safe, vault, one., may be pushed shutand locked in the. ordinary way.y As the door is closed, the lever Dmoves forward until its front end lstrikes against thc incline d, atwhich position the studz'has passed the guides c c, and the incline dmoves tlrc'lever laterally and places its wedge'funder the dogorsere-levei g. As the door of the safe, &c., is drawn open,theiwcdgefraises the dog y, which releases the hammer and lets itilyupon the cap and explodes it or thccharge in tue barrclfif there be abarrel connected, but ordinarily the muskct cap will sodndA a very loudalarm.

Having thus fully described my invention, what claim in burglars'alarms/for safes, vaults, and other Incoinhinatiou with a fire-arm lockon the inside of suchsafe or other apartment orreceptacle, a lever orarurconncctcd with the door thereof and"controlled by suitable guides,so that the act of closing the door from the outside shall conn-ect thelever or arm with' the dog or sere lever of thc-lock, and the lopeningot' said door trili the hammer and let it ily upon 'the cap or re acharge 'ot' powder, substantially as described.
